I hope this isn't old (it is, but I don't remember seeing it here), but these guys http://www.hwspirit.com/reviews.php?read=16&page=1 immersed a computer in sunflower oil, and it worked fine, and ran cooler (by 5 deg. C), and stayed cooler after running for a long time.

interesting choice of coolant, that's for sure

while we're at it, any of you cats know of a substance that has a low viscosity, high heat capacity, low freezing point, and is non-conductive? I was looking at an alcohol-immersion rig at one point, but there are a lot of snags with that (flammable and hydrophilic)... I'm guessing there isn't really one and that's why Flourinert sells for 3000$ a gallon or whatever, but it'd be nice if there were

That's gotta be a bitch to work on.

there are several older oils liek that, not sure of names offhand. We use them on some ancient elevators. The entire controller ,relays and motor contacters included, sits down in a 200 gallon tank of oil for spark supression. Lets it be used in an explosive enviroment.

i remember seeing that shit in a cray supercomputer a while back. it's interesting to see.

sounds like the sunflower oil might be what you're looking for. it's got a fairly low freezing point, isn't electrical conductive, but is fairly thermally conductive, is low viscosity as far as oils go, and can be obtained fairly pure so as to prevent corosion and other such natyness...
